It may be news to you that my legs don't work so hot right now. I not-so-lovingly refer to them as "those tubes of meat down below my hips." In addition, my knees have shown a tendency to buckle at random moments. As a result, walking at all, and particularly using stairs, is...difficult at best.
A couple weeks ago, while I was making my way carefully down the stairs, one of my knees gave out and I pitched headfirst down the stairwell. By some miracle, Adam happened to be walking up the stairs at the time and caught me before I smashed my skull open. Talk about knight in shining armor.
After this terrifying incident, whenever I needed to go downstairs, I would just sit on the top step and scoot down one stair at a time. It was clunky, but safe.
My doctor had me sign up for some physical therapy sessions. He found out how I was approaching the stairs and chuckled.
"Can I teach you a trick?"
Me, eagerly: "Of course."
"When you're standing at the top, turn around, hold the bannister, and walk down backwards."
So simple it's stupid.
